To all whom it may concern.'

Be it known that l', OsoAnC. Krans, Jr.,

had to the accompanying drawings, which form a part of thisspecification. v

My invention relates to carbureters, and

consists in the improvements hereinafter described and pointed out inthe claims.

In the accompanying drawing, Figure 1, is a sectionv oiia 1*verticalplane of' an apparatus'lembotlying my invention. Fig. 2, is a planfviewof the same in section on the line a, a, Fig. l. Fig. 3, is a detailedsectional view of the plug f, taken on the line 7), b, Fig. l. 'v

c, c, is the gasolene reservoir; d, d, is a basin extending into thereservoir c concentric therewith. The reservoir o has a concentricopening c in its bottom.

d1 1s a hollow cylindrical projection eX- tending downward from thebasin d; theinterior of the basin around the opening from the projectionZ1 is finished accurately conical and provided with an annular ridge g1concentric therewith and bounding thev accurately finished conicalsurface of the bottom of said basin.

f' is-a plug formed to fit in the interior of the projection Z1 andhaving a flaring conical head adapted to iit against the bottom of thebasin Z adjacent to the opening of the projection d1 and between thecontiguous portions of the bottom of the basin and of the head of saidplug and the ridge f/l the lower conical portion of y,said head is outaway, by` turningfin a lathe, so as to leave a surface parallel andclosely adjacent'to the surface of the bottom of said basin, as shown inFig. 1. The periphery of the head of said plug is so formed that itshall form a lvertical cylindrical surface adjacent and 'tom of thereservior o and is fitted with a nut e1 by which theV basin is securelyfastened 1n positlon upon the reservoir c.

Asetfscrew f1 may pass through the projection all into the plug f tohoidthe latter firmly in position.

l f2, f2 are horizontal apertures formed through the plug f andregistering with corresponding apertures through the projection d? so asto 'form a passage for the gasolene from the reservoir o.

t is a vert-ical passage from the aperture f2 having a valve seat at itsupper end against which the end of a needle valve j is adapted to littoregulate the size of the opening through the passage t.

f* (Figs. 1 and 3) indicates vapertures formed horizontally through theplug f so as to open at their outer ends at the lower conical surface oithe head' of which isslightly raised from the bottom of the lbasin d.The passage t opens into the aperture f4.

cl2 is a flange extending outward from the top of the basin d, andrestingr unon he upper edge of the reservoir o.

C1 is a hollow' cylindrical projection or extension from the top of thebasin d.

C2, C3 are` cylindrical screw-threaded apertures adapted to receiveconductor pipes, which apertures open through the wall of thecylindrical project-ion C1 opposite each other. It is a cylindricalshell fitting closely and adapted to turn in the projection- Cl and haveopposite apertures f1.1, h2 through its wall, which apertures areadapted 'to register respectively with the openings from the aperturesC2, C3.

7c isI a cover secured to the cylindrical projection C1 and adaptedto'close the upper end of the same. I

h3 is a cylindrical stem extending troni a part z'y of the shell hthrough a corresponding.

aperture in the cover 7c.

m is a. handle secured to the out-er end of the stem h3 by which theshell it may be rotated in the projection C1. j
